Technological progress is the application of scientific discoveries to production processes. Progress means that production costs are brought down or that new markets are born. Indeed, it is precisely the entrepreneurs who seek to invest in scientific research through an innovative spirit.
Technological progress has contributed to the improvement of living
conditions, increasing their duration.
However, this kind of progress has not reached every place in the world,
since the so-called ‘third world’ is still behind on this front.
Another substantial issue related to technological progress is one of its
consequences, that is environmental pollution. Due to the use of non-renewable
resources, alternative ways are now being sought to reduce this problem. Below
are a few different actions which can help our planet in the battle for its
survival.
Paint that fights pollution
Paints are a source of air pollution as they contain chemicals that evaporate easily (including formaldehyde and benzene). Two different uses have been studied to try to make paints sustainable:
1. Paints that produce energy: An Australian team has discovered that it is possible to produce hydrogen using sunlight and humidity in the air. So, according to scientists, this paint is capable of breaking down the elements of the water molecule just exposed to the sun to produce electricity.
This type of solar paint is already in use in the United States. Through graphene, which gives a high thermal conduction capacity, it is possible to keep the temperature of the surface on which the paint has been applied constant, avoiding a waste of energy.
2. CO2 capture paint: This paint is made from concrete that is capable of absorbing up to 20% of its own weight. This happens thanks to the chemical process of carbonation, through which the paint is able to absorb the surrounding CO2. This paint is called Celour.

Green newspaper
The Mainichi project will definitely turn to this direction: it is a
newspaper, made with a particular oil card that, after planted, can give life
to a splendid plant.
The initiative has already achieved Japanese schools with the hope of
teaching even the children the importance of recycling and respect for the
environment.
